title: Development of novel 2-[4-(aminoalkoxy)phenyl]-4(3H)-quinazolinone derivatives as potent and selective histamine H3 receptor inverse agonists.
abstract: Novel 2-[4-(aminoalkoxy)phenyl]-4(3H)-quinazolinone derivatives were identified as potent human H(3) receptor inverse agonists. After systematic modification of lead 5a, the potent and selective analog 5r was identified. Elimination of hERG K(+) channel and human alpha(1A)-adrenoceptor activities is the main focus of the present study.
